Description

Unpacking device and automatic production system

Technical Field

The application relates to the technical field of automation equipment, in particular to an unpacking device and an automatic production system.

Background

Today, to facilitate the transport of materials, the materials are often packaged in cartons. This makes it necessary to add a process of removing the material cartons during the actual production process.

The top surface of the carton is typically formed from two flaps that are attached to one another by means of an adhesive tape. As shown in fig. 1, an example of a top surface of a current adhesive tape sealed carton comprises a middle sealing adhesive tape and two side sealing adhesive tapes, wherein the middle sealing adhesive tape is attached to a butt joint of two hinges, the two side sealing adhesive tapes are perpendicular to the middle sealing adhesive tape, and joints of the two side sealing adhesive tape attaching parts and the side surfaces of the carton are folded.

In order to reduce the material from shaking and colliding in the carton during the conveying process, the inner wall of the carton is usually tightly attached to the material, and when the material is taken out from the carton, friction exists between the inner wall of the carton and the material. Nowadays, in order to enable materials to be taken out of a carton, the following two ways are generally used to realize the removal of the carton, namely, a first way is to cut the top wall and the bottom wall of the carton, lift the carton to enable the materials to slide down under the action of gravity, a second way is to separate the materials from the carton (for example, an unpacking system and a disassembling method disclosed in patent document CN101734391 a), and the top wall of the carton is cut, and the carton is turned over/poured, so that the materials are poured out from an opening formed by folding the hinge, and the separation of the materials from the carton is realized (for example, an intelligent unpacking machine disclosed in patent document CN 207712447U).

No matter which way is used for dismantling the paper box, the friction force given to materials by the inner wall of the paper box is overcome by means of gravity, the materials are easy to collide or scatter, and the materials are easy to damage in the unpacking process.

In addition, the operation of cutting the bottom wall and lifting the carton and overturning the carton is complex, so that the efficiency of removing the material carton is greatly influenced, and the process of removing the material carton is difficult to produce in the production rhythm of an automatic production system.
